Yeah I love a big load with the wand. I don't tamp but I do seat the load gently for the first hit or two, then I'll tap it against the heel of my hand to unseat everything, give it a shake, then tap the mouthpiece end of the wand gently, also against the heel of my hand to reseat, then heat again. 3 or 4 draws in total and it's dump time.
As for the angle of attack lol, I do hold it slightly uplifted whilst drawing, and that nipple end shape of the wand feels great if you rotate whilst drawing!
I get a lovely hit with a very even roast.
